ARTHUR WARNE, OF BUFFALO, NEW YORK.

FiRE-BOX FEEDER.

SPECIFICATION forming part of Letters Patent No. 236,385, dated January4, 1881.

Application filed July 6, 1880.

a full, clear, and exact description thereof, ref- A erence being had tothe accompanying drawings, and to the letters of reference markedthereon, making a part of this specification.

This invention relates to an improved apparatus for feedingdisintegrated or finelycoinminuted fuel-such as sawdust, tan-bark, andthe liketo furnaces by means of a forced blast of air; and it has forits objects to provide means by which the air required to carry the fuelmay be reduced in volume previous to entering the furnace without lossof the fuel, as more fully hereinafter specified. These objects laccomplish by the mechanism illustrated in the accompanying drawings, inwhich Figure 1 represents a perspective view of my apparatus, and Fig. 2a longitudinal vertical section thereof.

The letter A indicates ahorizontal tube, constructed of metal or othersuitable material, having a bend, B, about midway between To the forwardend of the said tube is adj ustably secured an enlargeddistributing-chamber, O, which projects through an opening, D, or thedoor of a furnace. The said tube, at its rear end, is provided with avertical extension, E,from the top of which extends a segmental tube, F,connecting with the main tube A just at the upper part of the bendthereof. The said extension E is open at one side, as indicated by theletter G, for the purpose hereinafter explained.

The letter H indicates an opening leading into the rear end of the tubeA, by which the said tube is connected to the fuel-supply tube leadingfrom the fan or other blast-generator, by which the airand fuel areforced to the furnace. The horizontal tube A, at the top of that portionlocated between the upright extension E and the connection of thesegmental tube F, is open, and is provided with a series of deflectors.The said deflectors are in the form of pivoted valves, as indicated bythe letter A, in the latter case being connected by a suitable link orlinks, I, with a bent le- (Model) ver, K, fulcrumed in standards L,whereby they may be operated simultaneously, for the purpose hereinafterset forth.

The distributingchamber O is provided at each side, near its mouth, withpivoted valves M, secured to the operating-levers N, by which they canbe opened or closed to any desired extent.

The operation of my invention is as follows: The blast of air, with thefuel, is forced into the opening at the rear of the tube A and passesforward into the same. On its passage it meets the inclined deflectors,and by them is deflected backward, causing a portion to escape, whilethe fuel, owing to its weight, is thrown to the bottom of the tube andis carried forward by the diminished blast to the furnace. In case thedeflectors or valves are opened to such an extent as to permit theescape of a portion of the fuel, such escaping fuel will be carried backto the open side of the vertical extension, and will enter the same andfind its way back to the horizontal tube, through the segmental tubebefore mentioned, the current of air through the horizontal tube servingto induce a current through the segmental tube and upright extensionsufficient to carry the fuel through the same.

Having thus fully described my invention and the method of itsoperation, what I claim, and desire to secure by Letters Patent, is

1. In combination with the horizontal feedtube, the hinged deflectors AA, the connecting-link l, and bent lever K, the whole adapted to operatesubstantially as specified.

2. In combination with the horizontal tube and its deflectors, thevertical extension, with the blowing apparatus and segmental tube,whereby any escaping fuel is taken up and returned to the horizontaltube, substantially as specified.

3. In combination with the horizontal tube, the distributing-chamber andits valves for directing the fuel into the furnace at any desired angle,substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand this28th day of June, 1880.
